一种新的无线电波传播路径损耗模型

Novel Path Loss Model for Propagation of Radio Waves

使用渗流网格建模无线电波的随机传播环境,在此基础上使用随机射线方法,从概率论的角度得到若干路径损耗的解析公式。经过与经典路径损耗模型以及其他由非波动方法得到的路径损耗模型的比较之后,从逻辑上推断出一个新的路径损耗模型。对新模型中参数的取值范围进行了讨论和分析,最后使用城市密集传播地区的测量数据验证新的路径损耗模型的精确性。

Percolation lattices are used to model random propagation environment of radio waves based on which stochastic ray method is utilized to analyze path loss from the perspective of probabilistic theory, and several closed-form expressions are derived. After the comparison with the classical results and the ones derived from other no-wave approaches, we propose a novel path loss model from logical deduction. The determination of model parameters is investigated and we validate this model by using the experimental data under typical dense urban propagation environment.
